Nowadays, the power system utility has started to consider the green power technology in order for the world to have a healthier environment. A small-scale hybridized solar PV-AC grid (HSPVACG) power system is proposed to be developed to operate with AC grid. This system consists of a photovoltaic array installed on the rooftop. Moreover the roof is flat, which implies that system can be placed...

This paper presents a control for a three phase three-level neutral point clamped inverter (NPC) for grid connected photovoltaic (PV) system. The maximum power point tracking (MPPT) is capable of extracting maximum power from the photovoltaic (PV) array connected to each DC link voltage level. The MPPT algorithm is solved by Perturb&Observe method. The MPPT system is integrated with the DC-link...

We consider the problem of automatically detecting small-scale solar photovoltaic arrays for behind-the-meter energy resource assessment in high resolution aerial imagery. Such algorithms offer a faster and more cost-effective solution to collecting information on distributed solar photovoltaic (PV) arrays, such as their location, capacity, and generated energy. The surface area of PV arrays, a...

The main objective of the paper is The growing concern for energy saving has increased the usage of LEDbased Street Lights, Electronic Chokes, Compact Fluorescent Lamps, And Inverter-Fed Drives. Hence, the load profile seen by the electrical grid is undergoing a notable change as these devices have to operate from a dc source. Photovoltaic (PV) being a major energy source, the loads can be conn...

This paper proposes a second-order harmonic reduction technique using a proportional-resonant (PR) controller for a photovoltaic (PV) power conditioning system (PCS). In a grid-connected single-phase system, inverters create a second-order harmonic at twice the fundamental frequency. A ripple component unsettles the operating points of the PV array and deteriorates the operation of the maximum ...

This work focuses on the modeling and analysis of a Standalone wind-PV Hybrid generation system under different conditions in MATLAB/SIMULINK environment. The proposed system consists of two renewable sources i.e. wind and solar energy. Modeling of PV array and wind turbine is clearly explained. The wind subsystem is equipped of a direct driven permanent-magnet synchronous generator, a diode re...

Four years׳ behavioral data of thin-film single junction amorphous silicon (a-Si) photovoltaic (PV) modules installed in a relatively dry and sunny inland site with a Continental-Mediterranean climate (in the city of Jaén, Spain) are presented in this article. The shared data contributes to clarify how the Light Induced Degradation (LID) impacts the output power generated by the PV array, espec...

Reformations in electricity sector along with various renewable energy promotion policies has increased the importance of small grid connected photovoltaic (PV) systems utilizing single-stage single-phase inverters. To improve the performance multilevel inverter are preferred over two levels. This paper proposes a single-stage five level inverter for grid connected (PV) system. The output curre...

The objective of this contribution is to present a new numerical approach for a complete design, optimum sizing, cost estimation (capital & $/kWh) and also evaluating the performance of solar photovoltaic/battery/diesel hybrid power systems. The world-wide demand for solar photovoltaic energy systems has grown steadily over the past 15 years. The need for reliable and low cost electric power in...

Photovoltaic power plants pose some challenges when integrated with the power grid. The PV plants always focus on extracting the maximum power from the arrays. This makes the PV system unavailable for helping in regulating the grid frequency as compared to conventional synchronous generators. A new technique for tracking a pseudo-maximum power point for creating power reserve is presented. This...
